Siteline

San Francisco, California, United States

Cash flow is the lifeblood of any contractor’s business, but billing is painful and slow. With so much manual work involved, a small, honest mistake can hold up millions of dollars in cash flow. And even when things go right, the time and effort it takes to get paid takes away from the work that really matters. We believe that when you free up payments, you free up people to take on whatever’s next. We started Siteline® to give construction teams a financial foundation to build on. Because when people are on the same page about getting paid, they can focus on whatever's next—whether that’s a new idea, a new project, or more time with their family. We’re reimagining construction finance to help contractors get paid, grow their business, and build a better future for all of us. Because when the foundation thrives, we all prosper.
